about £800 for a replacement standard engine

i wouldn't waste my time with a rebuild for 350bhp tbh

but if you really want to, forget the rods, throw whatever forged pistons you can get the cheapest in there and be done with it

When i say 350bhp thats what i want to be running when the build is done but when i get some more cash i want to uprate the turbo so i can get much bhp as i can out of it

It depends what one's you want to use fella, You could get CP pistons at about £300, But they would need a bit of work to fit a 100% ;-) .

Standard rods are fine up to 450 bhp as long as you have the ARP rod bolts, I bought HKS pistons at £450 from green line for my own car.

[huu-raa]

Machine a notch to clear the oil squirters.

And the same for any other non- GTiR specific pistons

I would stick with the standard compression ratio myself dude, Low comp engine's are notorious for being pants to drive off boost, And with the correct mapping you shouldn't need a low comp to get good results.
